Buying a desktop for bedroom

I'm thinking about buying a desktop to replace an old one we have in a upstairs bedroom, we have had lots of problems with internet connections with the present machine and have bought a external wireless adapter (I think that's what it is called) but that also loses internet connection often and we need to sync it back to the Virgin super hub downstairs very often and we are tired of it. Its not just the fact we have problems connecting to the internet the PC is really at the end of its life.

My question is what does the new PC need to have the best chance of finding/connecting to the downstairs modem? I realize laptops are better for finding/connecting wirelessly but I really need a desktop PC.

I agree with Pine Man as regards using Homeplugs, I also use Homeplugs.

But can you say why a laptop would not be suitable? I recently ditched my old desktop in favour of a laptop, I would not want a desktop again!

If it is because you don't like laptop built-in 'mouse' or touch pad use (both of which I don't like), then you could used a USB keyboard and a larger external Monitor connected to laptop - again, this is what I use! I also have an external hard-drive connected to laptop for keeping my Acronis backups.

The keyboard and monitor you are currently using will probably both work with a laptop.

Thanks Pine Man
So long as it works It need not be a wireless PC, I just took a quick look at the Homeplugs on Amazon around £40 for two, I dont know anything about them though, is it just a matter of placing them in the socket and away you go?
do I need just one for each PC, if this is so, is there any benefit using two for one PC say to get a better connection?

An added advantage of doing it my way, is that the only button used on the laptop is the On button - otherwise, the actual laptop is never touched, meaning that it is still in pristine condition after nine months use, it will probably still be in pristine condition after years of use!

Homeplugs - initially two are needed. One plugs into your Router and the Mains, the second connects to Ethernet socket on computer in bedroom and the mains - via Ethernet cables which are supplied with the plugs. Any number of single Homeplugs/computers can be added at any time, as long as they are all on the same Ring-Mains in the building.

I think I get the gist of that, but as the router is quite a way from the sockets in the living room if it needs a cable run to it it would need to be about 22 foot long, would this be standard or would I need to look for a special one?
